Description

Technical Field

[0001] The invention relates to the technical field of sound insulation material processing, and more particularly to a building sound insulation material and a processing method thereof. Background Art

[0002] Specialized soundproofing materials are increasingly used in all types of buildings to provide people with quieter living and working spaces. These materials are applied in a variety of ways, but generally follow a core principle, which is to effectively separate the sound source from the environment where the noise impact needs to be reduced. Traditional construction solutions mainly rely on covering or isolating to achieve this goal. For example, soundproofing materials are directly laid on the surface of building structures such as walls, ceilings or floors, and one or more layers of sound insulation are added to block or reduce the propagation of sound.

[0003] However, although these conventional construction methods can improve the sound insulation performance inside buildings to a certain extent, there are still some limitations. A major problem is that when sound insulation materials are attached to building structures such as concrete, wood or gypsum boards, the sound tends to penetrate the sound insulation layer through solid conduction and continue to propagate inside the building. This is because solid materials themselves have good sound transmission performance, especially when sound waves encounter the interface between different media, some sound waves can bypass the sound insulation materials or continue to propagate through the tiny gaps between the materials. Although existing building sound insulation materials and their construction methods have met people's needs for a quiet environment to a certain extent, they still face many challenges in practical applications, and the sound insulation effect still needs to be further improved and optimized.

DETAILED DESCRIPTION

[0029] A building sound insulation material includes a sound insulation body 1, which can be made of a hard material or an elastic body. Protrusions 2 are linearly distributed from left to right on the upper end surface of the sound insulation body 1. Each protrusion 2 is fixedly connected to the sound insulation body 1, and each protrusion 2 is provided with a flat mouth 2a.

[0030] Among them, the conduction direction of the flat mouth 2a is parallel to the sound insulation body 1, and the distribution direction of the protrusion 2 is consistent with the conduction direction of the flat mouth 2a. When the sound insulation body 1 is an elastomer, the Velcro quilt surface can be inserted and fixed into the flat mouth 2a of the protrusion 2 located at the edge, and the Velcro quilt surface can be inserted and fixed into the flat mouth 2a of the protrusion 2 at the other side edge. The Velcro quilt surface and the Velcro quilt surface are fitted and fixed, and the two free ends of the sound insulation body 1 are fitted to achieve end-to-end connection, and then tied with a cable tie. The sound insulation body 1 can wrap the sound source, and the protrusion 2 plays a role in separating the sound source from the sound insulation body 1. Thereby reducing the poor sound insulation effect caused by solid conduction. Similarly, when the sound insulation body 1 is a hard material, the sound insulation barrier sheet can be passed through all the flat mouths 2a to achieve double-layer sound insulation. The sound insulation sheet and the sound source are the first cavity, and the sound insulation sheet and the sound insulation body 1 are the second cavity. In fact, when the sound insulating body 1 is an elastic body, the sound insulating barrier sheet can also be passed through all the flat openings 2a.

[0031] Preferably, the protrusion 2 is fixed to the sound insulation body 1 by adhesive, and the sound insulation sheet is also fixed to the protrusion 2 by adhesive.

[0032] Preferably, a circular groove 2b is provided at the lower end of the protrusion 2 for storing adhesive, and the circular groove 2b is connected to the flat opening 2a so that the adhesive can also enter the flat opening 2a, so that the adhesive can fix the protrusion 2 and the sound insulation body 1, and can also fix the sound insulation sheet and the protrusion 2.

[0033] Preferably, the circular grooves 2b are distributed along the long side of the protrusion 2, and a connecting groove 2c is provided between any two adjacent circular grooves 2b to connect the two circular grooves 2b, so that the liquid adhesive can flow into the connecting groove 2c, increasing the range of the adhesive. The connecting groove 2c can also be connected to the flat mouth 2a, so that the excess adhesive in the flat mouth 2a can flow back to the connecting groove 2c, forming the adhesive required for the bottom of the protrusion 2 to be bonded.

[0034] In order to facilitate the processing of this special building sound insulation material, a building sound insulation material processing device is used, including a base frame 301, a box 302 is fixedly connected to the base frame 301, the box 302 is connected up and down, the box 302 is used to place the protrusion 2 with the bottom facing upward, the relative position between the protrusion 2 and the box 302 is maintained by friction, and the base frame 301 is fixedly connected to a first electric telescopic cylinder 401, the telescopic end of the first telescopic cylinder 401 is set downward, and a pressing plate 402 is fixedly connected to the telescopic end of the first telescopic cylinder 401, and a glue injection position 403 is set on the pressing plate 402, and the glue injection position 403 corresponds to the circular groove 2b in the longitudinal direction. The glue injection position 403 is used for the insertion of the glue injection part to limit the glue injection pipeline or the glue injection head to align with the circular groove 2b. The pressing plate 402 is driven by the first telescopic cylinder 401 to move up and down. The pressing plate 402 descends to enter the box 302 to push the protrusion 2 to descend and leave the box 302. When the pressing plate 402 is attached to the side of the protrusion 2 with the circular groove 2b, glue is injected into the circular groove 2b.

[0035] To further illustrate, a limit seat 501 is fixedly connected to the base frame 301, and the limit seat 501 is arranged below the box 302. A semicircular groove 502 is arranged at the front and rear ends of the box 302; a clamping seat is arranged inside the limit seat 501, such as Figure 8 As shown, the clamping seat includes a base 601, a first guide rod 602 is slidably connected to the base 601, a bevel platform 603 is fixedly connected to the left end of the first guide rod 602, a bevel with a lower left and a higher right is provided on the upper left part of the bevel platform 603, a spring 604 is sleeved on the first guide rod 602, the left and right ends of the spring 604 are in contact with the bevel platform 603 and the base 601 respectively, a first limiter is fixedly connected to the right end of the first guide rod 602, and the first limiter is against the right end of the base 601. Two clamping seats are arranged in mirror symmetry on the left and right sides, and the bevels of the two bevel platforms 603 are arranged facing each other. When the protrusion 2 is pushed down by the pressing plate 402 to disengage from the box 302, the protrusion 2 will further fall onto the limit seat 501, at which time the circular groove 2b of the protrusion 2 is still facing upward, and the left and right ends of the lower end of the protrusion 2 are respectively seated on the bevels of the two bevel platforms 603.

[0036] Further explanation, the front and rear sides of the left side of the base frame 301 are rotatably connected to a lead screw 801, the thread rotation direction of the two lead screws 801 is the same, the tops of the two lead screws 801 are synchronously driven through the first pulley belt assembly, the front and rear ends of the left side of the base frame 301 are respectively fixed to a second guide rod 802, the lower end of the second guide rod 802 is fixed to a second limiter, the base frame 301 is fixed to a motor 803, the output shaft of the motor 803 and the top of one of the lead screws 801 are synchronously driven through the second pulley belt assembly. A flip mechanism is set on the front and rear sides of the box 302, and for ease of explanation, the flip mechanism located at the rear side is taken as an example. The flip mechanism includes a displacement seat 701, on which a second electric telescopic cylinder 702 is fixedly connected, the telescopic end of the telescopic cylinder 702 is arranged forward, a first motor 703 is fixedly connected to the telescopic end of the second telescopic cylinder 702, the output shaft of the first motor 703 is arranged forward, a contact piece 704 is fixedly connected to the output shaft of the first motor 703, the axis of the first motor 703 is arranged coaxially with the semicircular groove 502, and the axis of the semicircular groove 502 coincides with the center of the protrusion 2 located on the two inclined platforms 603. The two displacement seats 701 are respectively spirally driven on the two lead screws 801, and the two displacement seats 701 are respectively slidably connected to the two second guide rods 802. The two second telescopic cylinders 702 are used to adjust the distance between the two contact pieces 704 to reduce the distance between them, so that the two contact pieces 704 are clamped at the front and rear ends of the protrusion 2. Then, the second motor 803 is started to rotate the two lead screws 801 synchronously, driving the two bases 601 to rise synchronously, so that the contact piece 704 drives the protrusion 2 to rise and leave the displacement seat 701. In this process, the adhesive in the protrusion 2 has slowly penetrated into the flat mouth 2a and the connecting groove 2c. Then, the first motor 703 is started to drive the contact piece 704 to rotate around the output shaft of the first motor 703, so that the contact piece 704 is used to clamp the protrusion 2 and flip it, so that the side of the protrusion 2 with the circular groove 2b faces downward. The inclined surface of the displacement seat 701 has two functions, one of which is to reduce the distance that the protrusion 2 rises, so that the protrusion 2 does not touch the displacement seat 701 when it is lifted and flipped. The second function is to make the pressing plate 402 further descend to press the protrusion 2 away from the contact piece 704 and to press the protrusion 2 to press the slopes of the two inclined platforms 603. At this time, any one of the inclined platforms 603 is subjected to a downward force component and a force component away from the other inclined platform 603, and the two inclined platforms 603 are separated until the protrusion 2 is clamped by the two inclined platforms 603. Before the two inclined platforms 603 are separated, the third telescopic cylinder 804 is fixed to the base frame 301 to drive the base frame 301 to descend, so that the two inclined platforms 603 first descend to press the sound insulation body 1, so that a concave indentation appears on the elastic sound insulation body 1. Then, the pressing plate 402 presses the protrusion 2 downward, and the lower end surface of the protrusion 2 protrudes from the bottom of the inclined platform 603 and is pressed into the indentation of the upper end surface of the sound insulation body 1.It is worth noting that the distance between the two inclined platforms 603 is smaller than the distance between the circular grooves 2b, so that the arch between the two indentations of the sound insulator 1 is located in the circular groove 2b, so that the adhesive in the circular groove 2b can overflow onto the indentation. As the elastic body recovers, the adhesive on the indentation can be bonded between the lower end surface of the protrusion 2 and the sound insulator 1, playing the role of spreading the adhesive covering the position. The position of the sound insulator 1 is adjusted by the transmission belt conveyor and transported to the bottom of the two inclined platforms 603.
